1.0.0: The external demo website worked very well, the demo web page does not work and the manual code does not. Here’s the problem “SecurityError (DOM Exception 18): Blocked a frame with origin “https://fiddle.jshell.net” from accessing a frame with origin “https://jsfiddle.net”. Protocols, domains, and ports must match.” The element look very promising.
Update 1: My guess is that this element does not work locally.
